Your doctor is an ENT. [quote]Otolaryngology (pronounced oh/toe/lair/in/goll/oh/jee) is the oldest medical specialty in the United States. Otolaryngologists are physicians trained in the medical and surgical management and treatment of patients with diseases and disorders of the ear, nose, throat (ENT), and related structures of the head and neck. They are commonly referred to as ENT physicians.[/quote]
As EZJim pointed out, an oncologist is any type of doctor or dentist who treats Cancer. As far as a second opinion, the general consensus on this board has been to seek one from an integrated team at a CCC (comprehensive Cancer Center). Your current doctor can arrange to have all the tests etc sent to a CCC. There not only an ENT surgeon but also a doctor of radiology (RO) and a doctor dealing with chemo (MO) all collaborate on a TX plan. My ENT had it all done for me at Georgetown University CCC Lombardi Cancer Center.
Good luck
